Driven by the deepening implementation of "dual-carbon" policies and increasingly stringent safety regulations for mining and tunneling operations, the pneumatic rock drilling mach

The Down-the-Hole (DTH) drill is a star piece of equipment in open-pit mines, drilling precise blast holes into rock much like a pangolin. Its impact mechanism is housed at the fro

The hole diameters for WC DTH (Down-The-Hole) drills typically range from 50 mm to 300 mm, depending on the specific design and material of the drill bit. These tools are suitable

The DTH drill is a piece of equipment that performs drilling through the combined action of impact and rotation, primarily used for operations in rock formations.

There is no fixed answer to how many meters a Down-The-Hole (DTH) drill can complete in a day, as efficiency depends on various factors. Generally, in medium-hard rock, a high-perf

Drilling diameter: 80–120 mm | Rock hardness (f): 8–16 Drilling depth: 30 m | Drill feed stroke: 1000 mm Drill rotation speed: 0–90 rpm Rotation motor power: 4 kW

The XQZ130 DTH (Down-The-Hole) drill rig features a drilling diameter of 90–130 mm, a drilling depth of 28 m, and drill rod specifications of Ø68/Ø76 mm; it is powered by a 242 kW

The drilling assembly consists of drill rods, button bits, and an impactor. Drilling is performed by connecting two drill rods in sequence. The rotation and air-supply mechanism co
